According to an embodiment, the display 220 may display a captured image, based on the control of the processor 210. Also, the electronic device 200 may obtain a user input through the display 220 and forward the user input to the processor 210.

According to an embodiment, the camera 230 may capture an image (e.g., a photo, a video, etc.) related to an object, a background, etc. Also, the camera 230 may include a stereo camera, an RGB camera, and a 3D camera.

According to an embodiment, the sensor 240 may include an image sensor, an acceleration sensor, an inertial sensor, a position detection sensor, and the like.

According to an embodiment, the memory 250 may be connected to the processor 210 and the sensor 240, etc., and may store various data.

The electronic device 200, the processor 210, the display 220, the camera 230, the sensor 240, and the memory 250 of various embodiments may perform various operations or functions that are not limited to those mentioned in the above description.

FIG. 3 illustrates a software construction of an example electronic device according to various embodiments.

According to an embodiment, the electronic device 300 may control various software to operate when an AR application 301 is executed. Control of the electronic device 300 may be performed by the processor 210 described above with reference to FIG. 2 , and the electronic device 300 may include the same or similar hardware construction to that of the electronic device 200.

Various software may include an input detection module 310, an update & render module 320, a 3D space coordinate generating module 330, an object management module 340, and a 3D space coordinate filter module 350.

According to an embodiment, the input detection module 310 may receive and process a user input. For example, the input detection module 310 may determine and correct a position, a type, a trajectory, a number, coordinates, etc. of a user's 2D input.

In an embodiment, the input detection module 310 may define and manage various inputs internally. For example, the various inputs may include an input of selecting a 3D object to be arranged, a touch down, a touch move, a touch up, and the like. Specifically, for example, the touch down may be an input in which a user starts a new touch, the touch move may be an input in which a touch is continuously maintained following a previous touch, the touch up may be an input in which a touch is terminated, and the like. The input detection module 310 may distinguish inputs such as the touch down, the touch move, and the touch up, based on an internally defined rule.

In an embodiment, the input detection module 310 may determine the validity of input. Also, the input detection module 310 may correct or ignore an input from a user according to the validity determination. For example, when the user provides an unintentional hand shake while inputting, the input detection module 310 may correct or ignore the user's unintended input caused by the hand shake. The input detection module 310 may internally define a criterion (or criteria) of validity determination of the input, and determine the validity of the input.

In an embodiment, the input detection module 310 may deliver two-dimensional (2D) input information (e.g., 2D touch coordinate and corrected 2D input information) among input information, to the update & render module 320. For example, when a 2D trajectory is obtained based on a user input, the input detection module 310 may deliver information about the 2D trajectory to the update & render module 320.

In an embodiment, the update & render module 320 may be divided into an update module 321 and a render module 322. The update & render module 320 may perform various processes for an overall operation of the AR application 301, and various processes of configuring and updating a display screen.

In an embodiment, the update module 321 may manage a user input and/or information necessary for arranging or displaying a 3D object in a 3D space coordinate system. For example, the update module 321 may deliver the information necessary for arranging the 3D object in the 3D space coordinate system, to each software. Also, the update module 321 may request 3D space coordinate information from the 3D space coordinate generating module 330 in order to obtain the 3D space coordinate information. The 3D space coordinate information may include information necessary for transforming 2D coordinates corresponding to a 2D input into 3D space coordinates. Also, the update module 321 may deliver the 3D space coordinate information to the 3D space coordinate filter module 350, and receive filtered (or corrected) 3D space coordinate information.

In an embodiment, the render module 322 may perform a process that a user may recognize through a display screen of the electronic device 300. For example, the render module 322 may arrange a 3D object at 3D space coordinates of the 3D space coordinate system. For example, the render module 322 may perform a graphic processing operation of arranging the 3D object at 3D space coordinates of an image obtained based on the camera 230 and the sensor 240.

In an embodiment, the update & render module 320 may transform 2D coordinates corresponding to a user's 2D input into 3D space coordinates of the 3D space coordinate system. For example, when a user performs a 2D input of touching a display, the electronic device 300 may set 3D space coordinates at which a 3D object is to be located. For example, the electronic device 300 may arrange the 3D object in a position (e.g., an arrangement point) on specific 3D space coordinates of the 3D space coordinate system separated by a specific distance in a direction in which the camera 230 is looking (facing). As another example, the update & render module 320 may transform 2D coordinates inputted by the user on the display, into 3D space coordinates, based on a distance to an arrangement point in the electronic device 300 and/or a view matrix and projection matrix provided by the 3D space coordinate generating module 330.

In an embodiment, the 3D space coordinate generating module 330 may provide a 3D space coordinate system and 3D space coordinates. For example, a user may execute the AR application 301 and scan a surrounding space through the camera 230 and the sensor 240 of the electronic device 300. The 3D space coordinate generating module 330 of the electronic device 300 may scan a surrounding area of the electronic device 300, based on the camera 230 and the sensor 240, and provide the 3D space coordinate system.

In various embodiments, the 3D space coordinates in the 3D space coordinate system may be expressed as a view matrix or a projection matrix.

In an embodiment, the object management module 340 may include an object status management module (or an “object status manager”) 341, a random number generating module (or a “random number generator”) 342, and a 3-degree-of-freedom generating module (or a “3-DoF generator”) 343. The object management module 340 may control an arrangement attribute of a 3D object, such as a rotation, a size, an interval, etc. of a 3D object, required for arrangement of the 3D object.

In an embodiment, the object status management module 341 may store predefined object settings in its own memory (not shown). For example, the object settings may include a set of 3D objects, a detailed arrangement method related to the arrangement of 3D objects, and the like. Also, the user may select at least one of predefined object settings, and the object status management module 341 may manage an object status, based on the object settings selected by the user.

In an embodiment, the object settings may be additionally defined by the user as well. For example, when the user additionally defines new object settings, the update & render module 320 may deliver them to the object status management module 341, based on a user's additionally defined input.

In an embodiment, the object settings may be defined by various methods. The object settings may be defined, for example, by a method of changing a rotation, a size, etc. into a predetermined value or ratio whenever a 3D object is arranged, a method of changing based on a random value, a method of using a combination of the above methods, etc. For another example, there may be a method of using a parameter used to arrange a previous object (e.g., a 3D object) as well. In this case, the object status management module 341 may obtain additional elements such as a velocity, an angular velocity, etc. for elements such as a rotation, a size, etc. of the 3D object, and use the additional elements when providing a next parameter.

In an embodiment, the object status management module 341 may receive an object status from the update & render module 320. The object status may be, for example, first object arrangement, intermediate object arrangement, last object arrangement, and the like. The object status management module 341 may provide a parameter necessary for arrangement of a 3D object, based on the received object status and object settings, using the random number generating module 342 and the 3-degree-of-freedom generating module 343. The object status management module 341 may deliver the object settings to the 3-degree-of-freedom generating module 343.

In an embodiment, the random number generating module 342 may provide a random value. The electronic device 300 may arrange a 3D object, based on the random value provided by the random number generating module 342. For example, the electronic device 300 may arrange various types of 3D objects in a predetermined order, or may arrange them in a random order, based on the random value. For another example, the electronic device 300 may arrange 3D objects at regular intervals, or may arrange the 3D objects at random intervals, based on the random value.

In an embodiment, the random number generating module 342 may selectively determine whether to provide a random value according to a setting of the electronic device 300, a setting of a user, etc.

In an embodiment, the 3-degree-of-freedom generating module 343 may provide and store a parameter related to arrangement of a 3D object. For example, the 3-degree-of-freedom generating module 343 may receive object settings from the object status management module 341. Also, the 3-degree-of-freedom generating module 343 may prepare a parameter storage space according to a request from the object status management module 341. The 3-degree-of-freedom generating module 343 may newly provide a parameter of determining the arrangement of a next object (e.g., a 3D object), based on data stored in the parameter storage space and received object settings. The newly provided parameter may be used for object arrangement, and may be stored again in the parameter storage space. The electronic device 300 may repeatedly perform the above-described parameter provision and storage operations, and harmoniously arrange a plurality of objects.

In an embodiment, the 3D space coordinate filter module 350 may correct (or filter) 3D space coordinate information (e.g., a trajectory, etc.) and remove noise and the like. For example, the 3D space coordinate filter module 350 may remove or correct unnecessary information, such as noise included in newly obtained 3D space coordinate information (e.g., 3D space coordinates), through comparison with 3D space coordinate information previously obtained by the electronic device 300.

In various embodiments, the 3D space coordinate filter module 350 may selectively determine whether to apply the removal of noise, etc. through correction (or filtering) of 3D space coordinate information (e.g., a trajectory, etc.) according to the setting of the electronic device 300 or the setting of the user.

FIG. 4 illustrates an overall flow in which an example electronic device operates according to various embodiments. Operations 410, 420, 430, 440, 450, 460, 470, and 480 of FIG. 4 will be described with reference to FIG. 5 illustrating various embodiments related to a user interface (UI) of an application of an example electronic device.

According to various embodiments, the electronic device 300 may correspond to the electronic device 200 of FIG. 2 , and operations of the electronic device 300 may be based on the control of a processor (e.g., the processor 210).

According to an embodiment, in operation 410 and operation 510, the electronic device 300 may execute an augmented reality (AR) application. The electronic device 300 may execute the application when obtaining a user's application execution input. The execution input may be implemented in various methods, such as a method of touching an icon, a method of using a voice, and the like.

According to an embodiment, in operation 420, the electronic device 300 may obtain surrounding image data.

Referring to operation 520 of FIG. 5 , after the user executes the AR application, the user may point the camera 230 of the electronic device 300 toward an area where a 3D object is to be arranged. Also, the electronic device 300 may display a guide screen indicating that image data is being obtained immediately after the AR application is executed. The electronic device 300 may obtain data of feature points (e.g., an edge, a corner, etc.) existing on the guide screen. The electronic device 300 may obtain image data including distance data, 3D data, etc. in addition to the feature point data.

In an embodiment, when the guide screen is displayed, the electronic device 300 may not perform another operation until a sufficient number of feature points are secured. In this case, the user may perform a scanning operation (e.g., an operation of moving the electronic device 300 up/down/left/right, etc.) in order to quickly secure the feature points. The electronic device 300 may scan a wider area according to a range of the scanning operation.

In an embodiment, operation 420 and operation 520 may be pre-works necessary for the user to stably arrange various objects in a virtual 3D space.

According to an embodiment, in operation 430, the electronic device 300 may provide a 3D space coordinate system, based on the obtained image data. For example, the electronic device 300 may provide the 3D space coordinate system using the camera 230 (e.g., a stereo camera, a 3D camera, etc.) and the sensor 240 (e.g., a distance sensor, an acceleration sensor, etc.).

According to an embodiment, in operation 440, the electronic device 300 may obtain a first input of selecting a 3D object.

Referring to operation 530 and operation 540 of FIG. 5 , for example, the user can perform an input of entering a mode for selecting a 3D object (e.g., touching an icon of entering a mode of selecting an object) as shown in operation 530. When the electronic device 300 obtains the user input of entering the mode of selecting the 3D object, the electronic device 300 may convert to a mode of selecting the type, etc. of the 3D object.

In an embodiment, the electronic device 300 may obtain a first input in which the user selects a 3D object (e.g., a star-shaped 3D object) as shown in operation 540. For example, the first input may be an operation of tapping one of the buttons. When obtaining the first input, the electronic device 300 may return to a screen shown in operation 530 and enter a standby state for receiving a subsequent user input (e.g., a second input and/or the movement of the second input). Also, the electronic device 300 may obtain an input of selecting one of predefined object settings in an object selection mode as well.

According to an embodiment, in operation 450, the electronic device 300 may obtain a second input of selecting a first point on a display, and in operation 460, the electronic device 300 may map the first point to first coordinates 304 of a 3D space coordinate system. For example, the user may perform an input of touching the first point, in order to arrange the star-shaped 3D object as the first object on the display. The electronic device 300 may map the first point to the first coordinates 304 of the 3D space coordinate system, and the star-shaped 3D object may be arranged on the first coordinates 304.

According to an embodiment, in operation 470, the electronic device 300 may provide a 3D path, based on the movement of the electronic device 300 and the movement of the second input. For example, as shown in operation 550 of FIG. 5 , the user may provide a 2D path (e.g., a 2D trajectory) 303, based on the movement of the second input from the first point to another (e.g., predetermined) point on the display. The electronic device 300 may provide a 3D path (e.g., a 3D trajectory) 306 in the 3D space coordinate system, based on the 2D path 303.

Also, when the user performs an input (e.g., touch up) of stopping a touch, the electronic device 300 may determine coordinates (e.g., second coordinates 305) of the 3D space coordinate system corresponding to a point where the touch is stopped, as coordinates where the 3D path 306 ends. The 3D path 306 may be a path that is moved according to the movement of the second input from the first coordinates 304 to the second coordinates 305.

According to an embodiment, in operation 480, the electronic device 300 may arrange the 3D objects at a plurality of coordinates on the 3D path 306. For example, when the user performs an input (e.g., touch up) of stopping a touch, the electronic device 300 may arrange 3D objects (e.g., star-shaped 3D objects) 307 at a plurality of coordinates on the 3D path 306, based on object settings, as shown in operation 560 of FIG. 5 . For another example, since the arrangement on the 3D path 306 of the electronic device 300 is done in 3D, the arrangement may be done as shown in operation 561 of FIG. 5 , when viewed from the side. Also, in a state of operation 560 or operation 561, the electronic device 300 may repeatedly perform the arrangement of an additional 3D object 307.

FIG. 6 illustrates a detailed flow in which the AR application 301 of the example electronic device 300 operates according to various embodiments.

According to various embodiments, the electronic device 300 may correspond to the electronic device 200 of FIG. 2 , and operations of the electronic device 300 may be based on control of a processor (e.g., the processor 210).

According to an embodiment, in operation 601, the input detection module 310 may process a user input.

In an embodiment, the input detection module 310 may continuously check the user input from a time point when the electronic device 300 executes the AR application 301 to a time point when the AR application 301 is terminated, and may deliver data about the user input to other modules (e.g., the update & render module 320, etc.). For example, the input detection module 310 may continuously check an input of user's selecting a 3D object, an input of arranging the 3D object on a 3D space, an input of additionally arranging a 3D object on the 3D space, etc., and deliver this to the update & render module 320.

In an embodiment, the user input may be an input of touching a body part such as a finger, etc. on a display (e.g., the display 220), or touching using a tool such as a stylus pen, etc. Also, the user input may be a 2D input (e.g., a single-touch input (tap), an input of providing a 2D path, etc.).

According to an embodiment, in operation 602, the update & render module 320 may request information on 3D space coordinates to the 3D space coordinate generating module 330 in order to process the 3D object on the 3D space. The information on the 3D space coordinates may include, for example, information on 3D space coordinate provision and/or 3D space coordinate update.

According to an embodiment, in operation 603, the 3D space coordinate generating module 330 may provide and update the 3D space coordinate information. For example, the 3D space coordinate generating module 330 may provide a 3D space coordinate system or update the existing 3D space coordinate system, based on a camera (e.g., the camera 230), a sensor (e.g., the sensor 240), and image data (e.g., feature point data, distance data, 3D data, etc.). Also, the 3D space coordinate generating module 330 may repeatedly perform an operation of providing or updating the 3D space coordinate system while the AR application 301 is running The repetitively performed operation may be done regardless of the user input.

In an embodiment, the 3D space coordinate generating module 330 may estimate 6-degree-of-freedom (DoF) information including a position, a rotation direction, etc. in the 3D space coordinate system of the electronic device 300, based on the camera (e.g., the camera 230), the sensor (e.g., the sensor 240), the image data (e.g., feature point data, distance data, 3D data, etc.), etc.

In an embodiment, among 6-degree-of-freedom, 3-degree-of-freedom may include information on position or movement, and remaining 3-degree-of-freedom may include information on orientation. Among the 6-degree-of-freedom, the 3-degree-of-freedom may be expressed by x, y, and z values, and may present position information of the electronic device 300. The remaining 3-degree-of-freedom may be expressed by values of a rotation (pitch) about an x axis, a rotation (yaw) about a y axis, and a rotation (roll) about a z axis, and may provide orientation information of the electronic device 300. The estimating of the 6-degree-of-freedom information may not only detect the position information of the electronic device 300 and the movement information corresponding thereto, but also obtain the orientation information of the electronic device 300. The estimated 6-degree-of-freedom information may be basic information of displaying the 3D object on a display screen.

In an embodiment, the 3D space coordinate generating module 330 may repeatedly perform an operation of estimating the 6-degree-of-freedom information while the AR application 301 is running The repetitively performed operation may be done regardless of a user input.

According to an embodiment, in operation 604, the 3D space coordinate generating module 330 may deliver a view matrix and a projection matrix that are information on 3D space coordinates, to the update & render module 320.

According to an embodiment, the electronic device 300 may continuously and repeatedly perform operations 602 to 604, unless otherwise set.

According to an embodiment, in operation 605, the input detection module 310 may classify the user inputs and determine coordinates, etc. of the 2D inputs. For example, the input detection module 310 may perform a determination of classifying the type of input into an input of user's starting a touch, an input of moving a touch, an input of lifting a body part such as a finger, etc. and/or a tool such as a stylus pen, etc. on the display in order to end the touch, and the like. For another example, the input detection module 310 may determine coordinates, etc. of a 2D input inputted by the user as well.

In an embodiment, the input detection module 310 may deliver information of distinguishing the user input, information on the coordinates of the 2D input, and the like, to the update & render module 320.

According to an embodiment, in operation 606, the update & render module 320 may transform coordinates of the user's 2D input into 3D space coordinates. For example, the update & render module 320 may receive information about the user's 2D input from the input detection module 310. The information on the 2D input may include the coordinates of the 2D input, a position of the 2D input, and the like. The update & render module 320 may transform the coordinates of the 2D input into the 3D space coordinates, based on 3D space coordinate information obtained from the 3D space coordinate generating module 330 (e.g., mapping 2D coordinates to 3D coordinates on the 3D space coordinate system). For example, there may be a case in which an input (e.g., a second input) of user's selecting a 3D object (e.g., a star-shaped 3D object) to be arranged and then arranging the 3D object is provided as a 2D input on the display. As obtaining the second input, the electronic device 300 may transform the 2D input into 3D space coordinates in the 3D space coordinate system and arrange the 3D object at 3D space coordinates.

According to an embodiment, in operation 607, the update & render module 320 may send an object status, information (e.g., the 3D coordinates of the 3D object, etc.) on 3D space coordinates, and/or information on object settings, etc., to the object status management module 341 of the object management module 340.

In an embodiment, the object setting delivered from the update & render module 320 to the object status management module 341 may simply be an object setting selected by the user among predefined object settings, or be an object setting newly defined by the user.

In an embodiment, the update & render module 320 may determine an object status related to a condition of arranging a 3D object, based on the information on the 3D space coordinates and the user input (e.g., the second input and/or the movement of the second input). The object status may include, for example, states such as first object arrangement, intermediate object arrangement, and last object arrangement.

In an embodiment, the object status may correspond to a user input in a one-to-one ratio. For example, the second input (e.g., a touch down) may be a state of the first object arrangement, the movement (e.g., a touch move) of the second input may be a state of the intermediate object arrangement, and an input (e.g., a touch up) of end of the second input may be a state of the last object arrangement.

In another embodiment, even if the user input is the second input (e.g., the touch down), when an amount of change of 3D space coordinates is sufficiently large according to the movement of the electronic device 300, it may have the intermediate object arrangement state as well. For example, when the user moves the electronic device 300 without moving an input tool (e.g., a finger, a stylus pen, etc.) in a state in which the user performs the second input to the electronic device 300, it may have the intermediate object arrangement state because it may mean that the 3D coordinates of the 3D object are moved.

According to an embodiment, in operation 608, the object management module 340 may perform overall processing required for providing parameters necessary for object arrangement.

In an embodiment, the object status management module 341 of the object management module 340 may check the validity of the object status received from the update & render module 320 and perform a process for an appropriate operation.

For example, after receiving the object status (e.g., the first object arrangement), the object status management module 341 may receive a subsequent object status (e.g., the intermediate object arrangement and/or the last object arrangement). When receiving the same object status (e.g., the first object arrangement) twice in succession, the object status management module 341 may check the validity of the received object status and process it as invalid. The electronic device 300 may sequentially perform one or two or more object arrangements, based on the plurality of object statuses and the 3D space coordinate information.

According to an embodiment, in operation 609, the object status management module 341 may deliver the object status, the object settings, and the like to the 3-degree-of-freedom generating module 343. Also, when it is determined that the object status (e.g., the first object arrangement) is valid, the object status management module 341 may request to prepare a parameter storage space in the 3-degree-of-freedom generating module 343. For example, the 3-degree-of-freedom generating module 343 may provide the parameter storage space, and the object status management module 341 may manage the parameter storage space. Also, the object status management module 341 may delete the parameter storage space after the object status of the last object arrangement.

In an embodiment, the object status management module 341 may request the 3-degree-of-freedom generating module 343 to provide a parameter necessary for object arrangement according to the object status. For example, the 3-degree-of-freedom generating module 343 may newly provide a parameter for determining next object arrangement (e.g., the intermediate object arrangement, the last object arrangement, etc.), based on the data stored in the parameter storage space and the received object setting.

In an embodiment, the 3-degree-of-freedom generating module 343 may store and use information (e.g., a parameter necessary for object arrangement) used for arranging an already arranged object in order to harmonize with the already arranged object. For example, there may be a case in which a rotation angle of continuous object arrangement is a rotation angle of a predetermined difference with respect to a specific axis. In this case, the parameter storage space of the 3-degree-of-freedom generating module 343 may store a rotation angle of object arrangement, and may use the stored rotation angle for the arrangement of a continuous next object.

According to an embodiment, in operation 610, the 3-degree-of-freedom generating module 343 may request a random number (random value) from the random number generating module 342 in order to add a random element to a parameter that will be provided based on the object setting. The operation of requesting the random number (a random value) may be an optional operation.

According to an embodiment, in operation 611, the random number generating module 342 may provide a random value existing within a range of a predetermined value. For example, the range of the predetermined value may be a range of a value that the random number generating module 342 receives from the 3-degree-of-freedom generating module 343. Also, the 3-degree-of-freedom generating module 343 may set a range of the provided random value. The random number generating module 342 may deliver the provided random value to the 3-degree-of-freedom generating module 343.

According to an embodiment, in operation 612, the 3-degree-of-freedom generating module 343 may provide a parameter related to 3-degree-of-freedom (3-axis rotation direction), scale (size of object), and the like.

In an embodiment, the 3-degree-of-freedom generating module 343 may determine the type, rotation, size, etc. of an object to be arranged, based on the parameter related to the 3-degree-of-freedom (3-axis rotation direction), the scale (size of the object), and the like, the object settings, and/or the provided random value.

According to an embodiment, in operation 613, the 3-degree-of-freedom generating module 343 may deliver the parameter related to the 3-degree-of-freedom (3-axis rotation direction), the scale (size of the object), and the like to the update & render module 320.

According to an embodiment, in operation 614, the update & render module 320 may arrange the object (e.g., the 3D object) at 3D space coordinates on the 3D space, based on the 3-degree-of-freedom (three-axis rotation direction), the scale (e.g., the size of the object), and the information on the 3D space coordinates, and the electronic device 300 may display the arranged 3D object on a display screen.

FIG. 7 illustrates an example process of arranging a plurality of 3D objects according to a user input according to various embodiments.

According to various embodiments, the electronic device 300 may correspond to the electronic device 200 of FIG. 2 , and operations of the electronic device 300 may be based on control of a processor (e.g., the processor 210).

According to an embodiment, in operation 710, a user may provide an input trajectory on a display through a second input (e.g., touching the display with a finger), the movement of the second input (e.g., providing a trajectory through the finger on the display), and an input of terminating the second input (e.g., lifting your finger on the display). For example, the input trajectory based on the real user's second input may be a 2D curve as shown in operation 710 of FIG. 7 . In this case, the electronic device 300 may obtain a plurality of 2D coordinates on a 2D curve (2D trajectory).

According to an embodiment, in operation 720, the input detection module 310 of the electronic device 300 may analyze and process the user's second input. For example, the input detection module 310 may determine that the leftmost 2D coordinates by the second input are a touch down, the right-most 2D coordinates by the end of the second input are a touch up, and the remaining 2D coordinates by the movement of the second input are a touch move.

According to an embodiment, in operation 730, the input detection module 310 of the electronic device 300 may deliver information on the plurality of 2D coordinates and the second input described above, to the update & render module 320. The update & render module 320 may transform 2D coordinates into 3D coordinates of a 3D space coordinate system, based on 3D space coordinate information provided by the 3D space coordinate generating module 330. Also, the update & render module 320 may determine an object status, which is a condition of object provision and arrangement, based on the 3D space coordinate information, an object setting, and the user input. Also, the update & render module 320 may deliver the determined object status to the object management module 340.

According to an embodiment, in operation 730, the object management module 340 of the electronic device 300 may perform an operation(s) such as providing, storing, and deleting information of arranging an object (e.g., a 3D object), based on the received object status. For example, the object management module 340 may provide a storage space for storing information (e.g., a parameter) on object arrangement in relation to first object arrangement, and the first arranged object may be arranged in a specific size according to the object setting. Also, the object management module 340 may store information on a size of an already arranged 3D object and information on a total number of 3D objects, in the parameter storage space. For another example, the object management module 340 may provide information of adjusting a size of a 3D object (intermediate object and last object) to be arranged subsequently, based on the stored parameter and object setting. For example, the object management module 340 may provide information of transforming a size of a subsequently arranged 3D object into a size decreased or increased by a ratio (e.g., a predetermined ratio) from a size of a previously arranged 3D object. Or, the object management module 340 may provide information of adjusting the size of the subsequently arranged 3D object in proportion to the information on the total number of the arranged 3D objects. The object management module 340 may provide information of randomly changing the size of the 3D object according to a user's touch trajectory as well.

According to an embodiment, in operation 740, the electronic device 300 may arrange the plurality of 3D objects on a display screen of the electronic device 300, based on the information provided by the object management module 340. For example, the object management module 340 may provide information of transforming the size of the subsequently arranged 3D object into the size decreased by the predetermined ratio from the size of the previously arranged 3D object. In this case, the electronic device 300 may transform the plurality of 3D objects into the size decreased by the predetermined ratio from the size of the previously arranged 3D object, based on the above information, and arrange the plurality of 3D objects on the display screen of the electronic device 300.

FIG. 8A illustrates an example state of arranging a plurality of 3D objects with an arrangement attribute corresponding to an input attribute according to a user input according to various embodiments. The arrangement attribute corresponding to the input attribute may be a rotation angle or rotation direction of a 3D object dependent on a user input trajectory.

In an embodiment, an example operation of the object management module 340 and the like will be described referring together to FIG. 8A and FIG. 8C illustrating a state in which the plurality of 3D objects are arranged based on the arrangement attribute (e.g., a rotation angle, a rotation direction, a rotation axis, etc.) corresponding to the input attribute, based on a user input.

In an embodiment, the object management module 340 of the electronic device 300 may provide a storage space for storing information (e.g., a rotation angle parameter, a rotation direction parameter, a rotation axis parameter, etc.) on object arrangement in relation to first object arrangement, and may provide information of arranging a first arranged object at a specific angle with a criterion of a specific rotation axis according to an object setting.

In an embodiment, the object management module 340 of the electronic device 300 may store information on an already arranged 3D object (e.g., a rotation angle parameter of the 3D object, a rotation direction parameter of the 3D object, and/or a rotation axis parameter of the 3D object), information on a total number of 3D objects (e.g., a parameter of the total number of 3D objects), etc., in a parameter storage space.

In an embodiment, the object management module 340 of the electronic device 300 may provide information (e.g., a rotation angle adjustment parameter) of adjusting a rotation angle of a 3D object (intermediate object and last object) to be arranged subsequently, based on an object setting previously set by a user. For example, as shown in FIG. 8A, the object management module 340 may provide information of adjusting the rotation angle of the 3D object to be arranged, based on the object setting (e.g., arranging with a rotation angle difference of 45° for each object) preset by the user. The object management module 340 may provide information of arranging at an angle of 0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°, and 360° when there are nine 3D objects to be arranged. The electronic device 300 may arrange the 3D objects at angles of 0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°, and 360°, based on the information.

In an embodiment, the object setting of the electronic device 300 may be variously set in advance by the user for a rotation axis (e.g., x axis, y axis, z axis, etc.), a rotation direction (e.g., a counterclockwise direction, a clockwise direction, etc.), a rotation angle, an arrangement interval, and the like.

In an embodiment, the object management module 340 of the electronic device 300 may provide information of adjusting a rotation angle of a 3D object (intermediate object and last object) to be arranged subsequently, based on the stored parameter and object setting. For example, the object management module 340 may provide information of arranging a subsequently arranged 3D object at an angle of rotating a predetermined size from an angle of a previously arranged 3D object. Or, the object management module 340 may provide information of adjusting a rotation angle of a subsequently arranged 3D object to associate the subsequently arranged 3D object with information on a total number of arranged 3D objects. For example, when the total number of 3D objects is 6, 60° obtained by dividing 360° into 6 equal parts may be used as the rotation angle. Or, when the total number of 3D objects is 10, the object management module 340 may provide information of arranging 3D objects at 60°, 180°, 240°, 300°, 360°, 420°, 480°, 540°, 600°, and 660°, respectively, by using a preset 60° as a rotation angle. The electronic device 300 may arrange the 3D objects at 60°, 180°, 240°, 300°, 360°, 420°, 480°, 540°, 600°, and 660°, respectively, based on the information.

In an embodiment, the object management module 340 of the electronic device 300 may provide information of randomly changing a rotation angle, a rotation direction, a rotation axis, etc. of a 3D object. For example, as shown in FIG. 8C, the object management module 340 may provide information of randomly changing a rotation angle of each 3D object, such as a 60° difference, a 45° difference, etc. and may provide information of randomly changing even a rotation direction of each 3D object, such as a counterclockwise direction, a clockwise direction, etc. Also, the object management module 340 may provide information capable of randomly changing even a rotation axis, which is a basis of rotation, such as x axis, y axis, and z axis, or provide information capable of presenting one or more axes as the rotation axis.

FIG. 8B illustrates an example state of arranging a plurality of 3D objects with an arrangement attribute corresponding to an input attribute according to a user input according to various embodiments. The arrangement attribute corresponding to the input attribute may be the type of a 3D object dependent on a user input trajectory.

In an embodiment, the object management module 340 of the electronic device 300 may provide information capable of randomly changing the type of a 3D object, or capable of changing the type of the 3D object in a predetermined order, as shown in FIG. 8B. For example, the object management module 340 may provide information of allowing the electronic device 300 to arrange 3D objects randomly within a range of an object setting (e.g., a setting for a range of the 3D object type) set by a user. Also, the object management module 340 may provide information of allowing the electronic device 300 to arrange the 3D objects in a set order, based on the user's object setting (e.g., a setting for an arrangement order dependent on the 3D object type). For another example, the object management module 340 may provide information of allowing the electronic device 300 to arrange 3D objects belonging to a set of predefined 3D object types randomly, based on a user input of selecting the set. Or, the object management module 340 may provide information of allowing the electronic device 300 to arrange the 3D objects belonging to the set of predefined 3D object types in a predetermined order, based on the user input of selecting the set.

FIG. 8D illustrates an example state of arranging a plurality of 3D objects with an arrangement attribute corresponding to an input attribute according to a user input according to various embodiments. The arrangement attribute corresponding to the input attribute may be a rotation direction of a 3D object dependent on a progress direction of a user input trajectory.

In an embodiment, the object management module 340 of the electronic device 300 may provide information of changing the rotation of a 3D object, based on a user input trajectory. For example, the object management module 340 may provide information of arranging the 3D object in parallel to a progress direction of an input trajectory as shown in FIG. 8D. The electronic device 300 may arrange the 3D object in parallel to the progress direction of the user input trajectory, based on the information. For another example, the object management module 340 may provide information of arranging the 3D object perpendicularly to the progress direction of the input trajectory. The electronic device 300 may arrange the 3D object perpendicularly to the progress direction of the user input trajectory, based on the information.

Also, in an embodiment, the object management module 340 of the electronic device 300 may provide information of arranging a 3D object to form a specific angle to the progress direction of the input trajectory, and the electronic device 300 may arrange the 3D object to form the specific angle to the progress direction of the user input trajectory, based on the information as well.

FIG. 8E illustrates an example state of arranging a plurality of 3D objects with an arrangement attribute corresponding to an input attribute according to a user input according to various embodiments. The arrangement attribute corresponding to the input attribute may be the size of a 3D object dependent on a user input speed.

In an embodiment, the object management module 340 of the electronic device 300 may provide information of changing the size of the 3D object, based on a user input speed. For example, the object management module 340 may provide information of adjusting the size of the 3D object in proportion to an input speed and arrange the 3D object, as shown in FIG. 8E. Specifically, for example, the object management module 340 may obtain information on an input speed, based on a distance between coordinates of obtaining a user's arrangement input. The electronic device 300 may arrange the 3D object having the size proportional to the user input speed, based on the information on the input speed.

FIG. 8F illustrates an example state of arranging a plurality of 3D objects with an arrangement attribute corresponding to an input attribute according to a user input according to various embodiments. The arrangement attribute corresponding to the input attribute may be an expected arrangement position of a 3D object based on an object status and a 3D space coordinate.

In an embodiment, the arrangement of the 3D object may be performed based on object status and 3D space coordinate information received from the update & render module 320 of the electronic device 300.

For example, when a distance between 3D space coordinates is long, there may be a coordinate in which the 3D object is not provided. In addition to the received 3D space coordinate information, the object management module 340 may determine virtual 3D space coordinates corresponding to a position where a real user input trajectory is expected to exist. Also, the object management module 340 may provide information of arranging 3D objects at regular intervals. As shown in FIG. 8F, the electronic device 300 may arrange a 3D object in a position where a real user input trajectory is expected to exist.

Although not shown in FIGS. 8A, 8B, 8C, 8D, 8E, and 8F, there may additionally be various embodiments in which a plurality of 3D objects are arranged with an arrangement attribute corresponding to an input attribute according to a user input.

In an embodiment, the object management module 340 of the electronic device 300 may provide information of arranging the plurality of 3D objects with an arrangement attribute (e.g., an arrangement interval, a rotation angle, an arrangement size, etc. of a 3D object) corresponding to an input attribute (e.g., an input speed) according to a user input. For example, when a user input speed (e.g., a movement speed of a second input) is fast, the object management module 340 may provide information of arranging the 3D objects at narrow intervals. For another example, when a user input speed (e.g., a movement speed of the second input) is fast, the object management module 340 may provide information of increasing the rotation angle of the 3D object and arranging the 3D object. Also, when the user input speed (e.g., the movement speed of the second input) is fast, the object management module 340 may provide information of increasing a difference of arrangement sizes of 3D objects and arranging the 3D objects. The object management module 340 may provide various types of information according to a setting, without being limited to the above-described embodiments in information on a relationship between the user input attribute (e.g., the input speed) and the arrangement attribute.

In an embodiment, the object management module 340 of the electronic device 300 may provide information of arranging a plurality of 3D objects with an arrangement attribute (e.g., an arrangement interval, a rotation angle, an arrangement size, etc. of a 3D object) corresponding to an input attribute (e.g., an input pressure) according to a user input. For example, when a user input pressure (e.g., an intensity of the second input) is large, the object management module 340 may provide information of arranging the 3D objects at narrow intervals. For another example, when the user input pressure (e.g., the intensity of the second input) is large, the object management module 340 may provide information of increasing the rotation angle of the 3D object and arranging the 3D object. Also, when the user input pressure (e.g., the intensity of the second input) is large, the object management module 340 may provide information of increasing a difference of arrangement sizes of 3D objects and arranging the 3D objects. The object management module 340 may provide various types of information according to a setting, without being limited to the above-described embodiments in information on a relationship between the user input attribute (e.g., the input pressure) and the arrangement attribute.

In an embodiment, the object management module 340 of the electronic device 300 may provide information of arranging a plurality of 3D objects with an arrangement attribute (e.g., an arrangement interval, a rotation angle, and an arrangement size, etc. of the 3D object) corresponding to an input attribute (e.g., an input time) according to a user input. For example, when a user input time (e.g., a time for a user's second input) is long, the object management module 340 may provide information of arranging 3D objects at narrow intervals. For another example, when the user input time (e.g., the time for the user's second input) is long, the object management module 340 may provide information of decreasing a rotation angle of a 3D object and arranging the 3D object. Also, when the user input time (e.g., the time for the user's second input) is long, the object management module 340 may provide information of decreasing a difference of arrangement sizes of 3D objects and arranging the 3D objects. The object management module 340 may provide various types of information according to a setting, without being limited to the above-described embodiments in information on a relationship between a user input attribute (e.g., an input time) and an arrangement attribute corresponding to the input attribute.

FIG. 9 illustrates an overall flow in which an application of an example electronic device is operated when a 3D space coordinate filter is applied according to various embodiments. When the 3D space coordinate filter is applied, the electronic device 300 may additionally perform operations 615 to 616 between operations 601 to 606 and operations 607 to 614 described above.

In operation 615, the update & render module 320 of the electronic device 300 may deliver 3D space coordinate information to the 3D space coordinate filter module 350 in order to determine whether to remove noise included in the 3D space coordinate information or to ignore a user input. Also, the update & render module 320 may deliver the type of input to the 3D space coordinate filter module 350 in order to perform accurate filtering.

In an embodiment, the update & render module 320 may selectively perform an operation of delivering the 3D space coordinate information to the 3D space coordinate filter module 350. For example, when the 3D space coordinate filter is not applied, the electronic device 300 may perform operations 601 to 614, and when the 3D space coordinate filter is applied, the electronic device 300 may additionally perform operations 615 to 616 between operations 601 to 606 and operations 607 to 614.

According to an embodiment, in operation 616, the 3D space coordinate filter module 350 of the electronic device 300 may correct (or filter) current 3D space coordinate information, based on the received 3D space coordinate information. For example, there may be cases in which hand shake occurs during a user input process and thus an input occurs in an unwanted position, or coordinates inputted by a user are too close to previous touch coordinates. The 3D space coordinate filter module 350 may filter newly received 3D space coordinate information by comparing the newly received 3D space coordinate information with stored 3D space coordinate information, and deliver the filtered 3D space coordinate information to the update & render module 320. Also, the 3D space coordinate filter module 350 may store the filtered 3D space coordinate information.

In an embodiment, the 3D space coordinate filter module 350 may deliver information of ignoring 3D space coordinates themselves to the update & render module 320, and the 3D space coordinate filter module 350 may also deliver information of not performing a subsequent operation to the update & render module 320.

FIG. 10A illustrates an example process of arranging a plurality of 3D objects when applying a 3D space coordinate filter according to various embodiments. For example, a distance between user inputs may be quite narrow, and when the inputs are used for object arrangement as they are, objects may be unintentionally arranged close together. The 3D space coordinate filter module 350 may determine a distance between 3D space coordinates that are transformed based on 2D coordinates. Also, the 3D space coordinate filter module 350 may ignore the 3D space coordinates when a distance between the 3D space coordinates and previous 3D space coordinates is lower than a set value. The electronic device 300 may not perform operations 607 to 614 for the ignored 3D space coordinates. When the 3D space coordinates are ignored and operations 607 to 614 are not performed, the electronic device 300 may arrange 3D objects on a 3D space in a state (e.g., ignored intermediate object arrangement) of ignoring some of objects as shown in FIG. 10A.

FIG. 10B illustrates an example process of arranging a plurality of 3D objects when applying a 3D space coordinate filter according to various embodiments. For example, the electronic device 300 may filter out a predetermined amount of hand shake that may occur in a direction different from a progress direction (e.g., the movement of a second input) of an input actually intended by the user, based on a biquad filter. In a specific example, as shown in FIG. 10B, there may be a case in which, although a user has inputted (e.g., the movement of a second input) with the intention of making a straight 2D input, the user fails to draw a straight line, which is different from the user's intention. The 3D space coordinate filter module 350 may correct (or filter) current 3D space coordinate information wherein a user's 2D input becomes a straight trajectory, based on the received 3D space coordinate information.

FIG. 10C illustrates an example process of arranging one 3D object when applying a 3D space coordinate filter according to various embodiments. To provide a single object, a user may simply input a second input and an input of terminating the second input without moving the second input, to a screen. For example, the user may touch a display (e.g., the display 220) once with a finger or a stylus pen and then lift the finger or stylus pen. In this case, the input detection module 310 may divide a user input into subdivided inputs such as a touch down, a touch move, and a touch up as shown in FIG. 10C. Or, the input detection module 310 may divide into two inputs such as the touch down and the touch up in which the touch move is omitted. As described above, the 3D space coordinate filter module 350 may ignore when object arrangement is not made for 3D space coordinates corresponding to 2D coordinates provided in a short distance. The electronic device 300 may arrange one 3D object as shown in FIG. 10C.
